Gave my dodge good power for the hemi easy to install and better gas milage!

I was a little worried about buying these unbranded parts but I didn't want to pay 4 times as much at an auto parts store. I drive 80 miles a day to work and back and the misfire my truck developed was wasting gas. A couple thousand miles later and these are still as strong as new.

So I have been researching for some alternative price wise Coil Packs for my 2015-2024 Dodge Charger 5.7L Hemi R/T Road & Track. OEM Coil packs can set you back like shopping at Costco for milk (LOL) or doing grocery shopping (cause it's been 4 months and you really got to stock up the pantry).Anywho, While these look almost the same as the OEM there are some noticeable differences. For one, the mounting screws. These were a bit too short in length. So I thought I'd use the OEM and there were good until I ran into a noticeable problem.As my headline is stated above. They do not align well and I would say they are about a millimeter to 2mm off ( all I know, is that if I screw the top the bottoms is off. If I screw the bottom, the top is off. Then there is a gap and bottom of the epoxy side and the boot cover). No matter how much you try make it align. the screw mounts won't align and that is not good. Some here folks here say they fit fine and some say they don't. I'm with the latter. Even if you do use them, you will have a gap.Lastly, the other noticeable part is that the Coil Pack Boot. The Boot went straight down versus the OEM where one Boot is straight down and the other Boot is at a angle. Does it make it a difference? I don't know. I didn't get far enough to see if it mattered or not. Because the darn Coil Pack won't align and it has a gap. So I didn't want to take the chance.Now I don't have pics and I didn't want to waste time on showing proof while I was replacing 16 Spark Plugs and putting everything back together. But, if I had to revert to using my OEM (which by the is still good and there are no issues) I was just hoping to update my original OEM Coil Packs for longer life. But I will now have to some money so I can get the OEM Coil Packs.Granted everything is made in China and there is just one Manufacture that makes these Coil Packs and is marketed and sold by SO MANY names on Amazon and eBay Sellers. All the while using the same Sales Marketing Pics etc. It's just, that somewhere along the "contract use blueprints", Manufacturing Line and Quality Control, that one mis-alignment can cause this product to be taken off the shelf really quickly or stored on the shelf for a long time. I for one won't use these alternative priced products and force fit the coil packs.The choice is yours. My suggestion. Save up and buy OEM or at least high performance Coil packs from the likes of RIPP, Holley, Summit, or from NGK itself.Good Luck!

You really have to press down to get the bolts caught on the thread it figures I had the last one back to the firewall and it was a pain after spending a while I had to use a prybar to hold it down to get the bolts in but the truck runs great

Works great in 06 RT

Very nice and work good in my hemi and made the truck run so smooth and quitter then it ever has.
